Our experiment reported results from a haloscope search for axion dark matter, excluding the axion-photon coupling predicted by a benchmark model. The sensitivity was achieved through the use of a large-volume cavity, a superconducting magnet, an ultra low noise Josephson parametric amplifier, and subKelvin temperatures. The validity of the detection procedure was ensured by injecting and detecting blind synthetic axion signals.
We report the results from a haloscope search for axion dark matter in the 3.3-4.2 mu eV mass range. This search excludes the axion-photon coupling predicted by one of the benchmark models of invisible axion dark matter, the Kim-Shifman-Vainshtein-Zakharov model. This sensitivity is achieved using a largevolume cavity, a superconducting magnet, an ultra low noise Josephson parametric amplifier, and subKelvin temperatures. The validity of our detection procedure is ensured by injecting and detecting blind synthetic axion signals.
